The Geiger-Muller Tube

The Geiger-Muller Tube. The Geiger-Müller Tube’s Ionizing Radiation sensor detects low level beta and gamma radiation. It is possible to detect background radiation, as well as low level radiation, Emitted by radioactive sources, like potasium fertilizers or a gas lantern mantle.

  1. The Geiger-Muller Tube • The Geiger-Müller Tube’s Ionizing Radiation sensor detects low level beta and gamma radiation. • It is possible to detect background radiation, as well as low level radiation, Emitted by radioactive sources, like potasium fertilizers or a gas lantern mantle. • The sensor can be used as a counter to monitor counts (or counts per interval) from a radiation source or to measure the operating voltage applied to the GM tube

  2. It was named after Hans Geiger, who invented the device in 1908, and Walther Müller who collaborated with Geiger in developing it further in 1928. A Geiger-Müller tube consists of a tube filled with a low-pressure inert gas such as helium, neon or argon, and an organic vapor or a halogen gas and contains electrodes, between which there is a voltage of several hundred volts, but no current flowing. The walls of the tube are either metal or the inside coated with metal or graphite to form the cathode while the anode is a wire passing up the centre of the tube. The Geiger-Muller Tube
